Funny you asked. The short answer is no. But we did get a request to add
STV_EXPORT to the ELF visibility in gABI. Right now, we have STV_DEFAULT,
STV_INTERNAL, STV_HIDDEN and STV_PROTECTED. STV_EXPORT does exactly what
you were asking for. If I remembered right, it came from some C++ compiler
people :-).

I think we asked for more info on it and also we have very limited bits
left in st_other. Many people want to use them for different purposes.
